PROBLEM TO BE SOLVED: To obtain a large joining strength by almost uniformly heating different metallic materials having different electrical resistance. SOLUTION: The brazing method of joining the end faces of two different metallic materials 1, 2 having different electrical resistance is performed by abutting the two end faces with a filler metal 3 inserted in-between, energizing the electrodes 5 attached to both metallic materials 1, 2 to impart resistance heating to the opposing ends, and melting the filler metal 3 to join the two end faces of the two metallic materials 1, 2. In this method, the distance L2 from the joining face to the electrode in one metallic material 2 having a larger electrical resistance is made smaller than the corresponding distance L1 in the other metallic material 1 having a smaller electrical resistance. Then, the two electrodes 5 are energized in-between to join the end faces of both metallic materials 1, 2. COPYRIGHT: (C)2004,JPO |
